CoCo is now removed from the 5g and has been replaced by chewie.. CoCo now lives in chewies 2.5g home... It was so weird CoCo was great in the 5g for the first couple days... but all of a sudden it was like he though the snail was a betta... He was relentless! It was soooo weird! I couldn't leave him in there he would have killed the poor snail.
